[0002] An electrical equipment protection frame is a cabinet used to assemble electrical components. Its main function is to fix the electrical components and protect them from being exposed to harsh and dangerous environments.

[0003] Traditional electrical equipment protection frames are only used to position and electrically connect electrical components and to separate electrical components from the outside world. However, since the electrical components in the electrical equipment protection frame are in a circuit connection environment for a long time, both the electrical components and the outside of the protection frame are prone to fire. Since electrical equipment is generally arranged in a concentrated manner, it is necessary to ensure that the electrical equipment protection frame has a fireproof function. When a fire occurs in the external environment, the electrical components in the electrical equipment protection frame are prevented from being damaged. When the electrical components in the electrical equipment protection frame catch fire, the fire is prevented from spreading and the loss is reduced. Summary of the invention

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1 and Figure 3 The frame unit 1 includes a rectangular box 10, the outer end surface of the rectangular box 10 is coated with a fireproof coating 11, a ceramic box 12 is fixedly installed on the inner end surface of the rectangular box 10, and water is contained in the ceramic box 12. Air holes 13 are evenly opened on the rectangular box 10 and located at the upper end of the ceramic box 12. The upper ends of the air holes 13 on the rectangular box 10 are rotatably connected with elastic springs 14 through pins. A support column 15 is evenly fixedly installed on the inner end surface of the ceramic box 12. The support column 15 is a heat-insulating material, and the end of the support column 15 is fixed. A drying cabinet 16 is fixedly installed, and a heat insulation board 17 is fixedly installed on the outer end surface of the drying cabinet 16. An air outlet 18 is opened at the upper end of the middle part of the drying cabinet 16, and a radiator 19 is connected to the air outlet 18. A ventilation duct 20 is fixedly installed at the upper end of the air outlet 18, and the end of the ventilation duct 20 is fixedly connected to the ceramic box body 12. When in use, the rectangular box 10 is first positioned by the positioning unit 2, and then the electrical components are assembled as needed, and the drying cabinet 16 and the rectangular box 10 are closed. When a fire occurs, the fireproof coating 11 increases the heat insulation performance of the rectangular box 10 to achieve the purpose of delaying the structural damage time of the rectangular box 10. The boiling point of water is 100°C. Therefore, before the water in the ceramic box 12 is dried up, the maximum temperature of the environment where the drying cabinet 16 is located is guaranteed to be 100°C to prevent the heat insulation board 17 from being in a high temperature environment for a long time, reduce the temperature in the drying cabinet 16, and protect the electrical components in the drying cabinet 16. When the external working environment of the rectangular box 10 is suitable, the heat generated by the electrical components in the drying cabinet 16 is dissipated by the radiator 19. The gas is discharged out of the air outlet 18 and finally enters the ceramic box body 12 through the ventilation pipe 20. When the elastic spring piece 14 is subjected to a large extrusion force, the elastic spring piece 14 rotates to facilitate the gas to be discharged through the vent hole. There is no need to open another through hole for heat dissipation, which prevents the flame from entering the drying cabinet 16 through the through hole in case of fire and accelerating the damage of the electrical components. On the contrary, when the electrical components catch fire, the water in the ceramic box body 12 and the drying cabinet 16 cooperate to prevent the high temperature from affecting the surrounding electrical equipment and spreading the fire range.

When the box cover 102 is rotated backward, the elastic snap-in piece 108 enters the snap-in groove 104. When the box cover 102 needs to be opened, the round-headed extrusion column 107 on the left is pressed to make the round-headed extrusion column 107 on the right squeeze the elastic snap-in piece 108, and the round-headed extrusion column 107 is restored to its original position by the positioning spring 105. When a fire occurs, the water in the rectangular ceramic box 109 is used to control the ambient temperature of the fixed box 101 and the box cover 102. When the volume of the evaporating gas is large, the elastic spring leaf 2 110 is rotated by the squeezing force, and the excess gas is discharged from the rectangular ceramic box 109 through the air vent 2.

[0037] In specific operation, firstly, the movement of the rectangular box 10 is controlled by the universal wheel 21. When the rectangular box 10 moves to a suitable position, the threaded column 24 is controlled by rotating the control handle 22 to make the rectangular hollow part 26 move downward until the rubber suction cup 28 is in close contact with the horizontal plane.

Therefore, in the ceramic Before the water in the ceramic box body 12 is dried up, the maximum temperature of the environment in which the drying cabinet 16 is located is ensured to be 100°C to prevent the heat insulation board 17 from being in a high temperature environment for a long time, reduce the temperature in the drying cabinet 16, and protect the electrical components in the drying cabinet 16. When the external working environment of the rectangular box body 10 is suitable, the heat generated by the electrical components in the drying cabinet 16 is discharged from the air outlet 18 through the radiator 19, and finally enters the ceramic box body 12 through the ventilation duct 20. When the elastic spring leaf 14 is subjected to a large extrusion force, the elastic spring leaf 14 rotates to facilitate the gas to be discharged through the vent hole, and there is no need to open another through hole for heat dissipation, which prevents the flame from entering the drying cabinet 16 through the through hole in the event of a fire, thereby accelerating the damage to the electrical components.
